The Campi Flegrei are a unique place in the world, where geology meets history and myth intertwines with science. This vast volcanic caldera, located west of Naples, has hosted some of the oldest civilizations of the Mediterranean and continues to be a land in constant transformation. Through a journey between past and present, this book explores the complex nature of the Campi Flegrei: from the prehistoric eruptions that shaped its landscape, to the tales of Aeneas and the Cumaean Sibyl, up to the most recent scientific discoveries on bradyseism and volcanic risk. It tells the story of the greatness of the Phlegraean cities — Pozzuoli, Baia, Cuma, and Miseno — with their vestiges and the remains of an age of splendor. A work that combines archaeology, science, and legend, offering a complete portrait of a fascinating and unstable land, suspended between the fire of the earth and the allure of its millennia-old history.
